Heather’s Holistic Approach to Nutrition utilizes a myriad of diagnostic testing, for proper assessment, diagnosis and treatment of the patient. Determining the source of your imbalance, rather than managing it, creates balance. Heather will assess your current food and eating patterns, including when, from what source, and why you eat. This helps form the most effective wellness treatment plan and health strategy for the patient. Heather utilizes a myriad of progressive diagnostic and testing methods to determine the best course of treatments and therapies for patients. Some of these testing methods include intracellular vitamin and mineral testing, adrenal saliva testing, Skin allergy testing, urine neurotransmitter testing, advanced cardiovascular blood testing for determining cardiac risk and identifying biomarkers that can be altered with nutrients and diets to prevent the onset of cardiovascular events and disease. Additional test methods include Food & Environmental Antibody/Allergy Testing, Urine testing for toxic heavy metals as well as standard blood testing of endocrine markers. Heather has developed additional progressive dietary therapies and treatment plans for Autism, Alzheimer’s, Cardiovascular Disease, Metabolic Disorders, Food Allergies, Irritable Bowel Syndrome, Depression, other Mood Disorders, Menopause, and Heavy Metal Toxicity.

Dr. Chorig K., PharmD, Integrative Wellness & Life Coach received her Doctorate of Pharmacy from the University of Southern California. A leading thread throughout her life, her search for the true meaning of health has remained constant and passionate. She studied different nutritional models, healing protocols as well as Ayurveda. A longtime practitioner of yoga, she completed several teacher trainings with Shiva Rea and taught for five years in Paris, France.
Her continued exploration of the interconnectedness of the physical, emotional, mental and spiritual aspects of Self led her to Dr. Bruce Lipton’s groundbreaking work in epigenetics and quantum physics. In his work was the scientific proof that the invisible forces constituted by our thoughts, emotions and beliefs are the primary forces that control our bodies’ biology and physiology. She found the consequence of this paradigm most empowering for us human beings: by processing our emotions and clearing them, by shifting our thoughts and establishing new neuronal patterns in the brain, we have the ability to control our genetic expression. We are no longer victims of our heredity but masters of our genetic activity.
Having experienced the truth of this paradigm throughout her own healing journey, it is with empathy, compassion and intuition that Dr. Khatchadourian empowers her clients to become the architects of their own healing, the creators of their own unique destiny.
